# Slash Commands API
|
|
|
|
The Commands API lets plugins register `/` slash commands. When a user types `/` in the chat composer, MetoYou shows a Discord-style autocomplete menu of available commands. Selecting a command (click, `Enter`, or `Tab`) runs it — either immediately when it declares no options, or after the user types the requested arguments.
|
|
|
|
## Required Capabilities
|
|
|
|
| Method | Capability |
|
|
| --------------------------------- | ------------- |
|
|
| `commands.register(id, command)` | `ui.commands` |
|
|
| `commands.list()` | `ui.commands` |
|
|
|
|
Every registration returns a disposable. Push it into `context.subscriptions` so the command is removed when the plugin unloads.
|
|
|
|
## Command Scope
|
|
|
|
A command's `scope` controls where it appears:
|
|
|
|
| Scope | Available in |
|
|
| ------------------- | --------------------------------------------- |
|
|
| `global` (default) | Chat servers **and** direct messages |
|
|
| `server` | Only while a chat server is the active surface |
|
|
|
|
Use `global` for commands that work without a server context (e.g. `/help`, `/shrug`). Use `server` for commands that act on the current server, channel, or members.
|
|
|
|
## Options and Argument Parsing
|
|
|
|
Declare `options` to describe the arguments a command accepts. MetoYou parses what the user typed after the command name and passes the result to `run` as `context.args`, keyed by option name.
|
|
|
|
```ts
|
|
interface PluginApiSlashCommandOption {
|
|
description?: string;
|
|
name: string;
|
|
required?: boolean;
|
|
// 'rest' captures all remaining text; otherwise a single whitespace-delimited token
|
|
type?: 'string' | 'number' | 'boolean' | 'rest';
|
|
}
|
|
```
|
|
|
|
- Positional options are filled left-to-right from whitespace-delimited tokens.
|
|
- A `rest` option captures all remaining text verbatim (use it last, for free-form text).
|
|
- Missing positional values are passed as empty strings.
|
|
- The autocomplete menu shows required options as `<name>` and optional ones as `[name]`.
|
|
|
|
Values arrive as strings; convert `number`/`boolean` types yourself inside `run`.
|
|
|
|
## Command Context
|
|
|
|
`run` receives a context that extends the standard action context (`source: 'slashCommand'`) with the invocation details:
|
|
|
|
```ts
|
|
interface PluginApiSlashCommandContext extends PluginApiActionContext {
|
|
args: Record<string, string>; // parsed values keyed by option name
|
|
command: string; // invoked name without the leading slash
|
|
rawArgs: string; // raw text typed after the command name
|
|
// inherited: server, textChannel, voiceChannel, user, source
|
|
}
|
|
```
|
|
|
|
## Register a Command
|
|
|
|
```js
|
|
export function activate(context) {
|
|
const api = context.api;
|
|
|
|
// Server-scoped command with a free-form message argument.
|
|
context.subscriptions.push(
|
|
api.commands.register('announce', {
|
|
name: 'announce',
|
|
description: 'Post an announcement to the current channel',
|
|
icon: '📢',
|
|
scope: 'server',
|
|
options: [{ name: 'message', type: 'rest', required: true }],
|
|
run: (slash) => {
|
|
api.messages.send(`📢 ${slash.args.message}`, slash.textChannel?.id);
|
|
}
|
|
})
|
|
);
|
|
|
|
// Global command that works in servers and DMs.
|
|
context.subscriptions.push(
|
|
api.commands.register('shrug', {
|
|
name: 'shrug',
|
|
description: 'Append the shrug emoticon',
|
|
scope: 'global',
|
|
run: () => api.messages.send('¯\\_(ツ)_/¯')
|
|
})
|
|
);
|
|
}
|
|
```
|
|
|
|
`api.messages.send` requires the `messages.send` capability, so the example above declares both `ui.commands` and `messages.send` in its manifest.
|
|
|
|
## List Registered Commands
|
|
|
|
```js
|
|
const allCommands = context.api.commands.list();
|
|
```
|
|
|
|
Returns every slash command currently registered across all active plugins, including their scope and options.
|
|
|
|
## Built-in Commands
|
|
|
|
MetoYou ships first-party commands that are always available without any plugin, such as `/lenny` (posts `( ͡° ͜ʖ ͡°)`). They appear in the same autocomplete menu tagged as **Built-in**. Plugin commands are listed alongside them; if a plugin registers a command with the same name as a built-in, both appear and the user can pick either.
|
|
|
|
## How Input Is Handled
|
|
|
|
- Typing `/` opens the menu; typing more characters filters by command name (prefix matches rank first).
|
|
- Picking a command **without options** runs it immediately and clears the composer.
|
|
- Picking a command **with options** fills `/name ` so the user can type arguments, then `Enter` runs it.
|
|
- Slash input is intercepted and never posted as a chat message. Text that starts with `/` but matches no registered command falls through and is sent as a normal message.
